Tammy 2 is never too far away! The second ex-Mrs. Tammy Swanson, played by Megan Mullally, will pop up again in season 5 of NBC comedy Parks and Recreation. Would you be shocked to learn that this does not bode well for Ron Swanson (Nick Offerman), who is starting a romance with single mom Diane (guest star Lucy Lawless)? You would not.

“She does what she’s best at: trying to ruin Ron’s life,” executive producer Michael Schur tells EW of Tammy 2’s return, which was first reported by TVGuide.com. “It’s kind of the ultimate test of Ron’s relationship with Diane. And also the ultimate mission for Ron’s emotional guardian, Leslie Knope (Amy Poehler).”

Mullally, who stars on Childrens Hospital, is the real-life spouse of Offerman. Her guest spot is slated to air in late November.
